Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in AncoraThemes Exit Game exit-game allows PHP Local File Inclusion.This issue affects Exit Game: from n/a through <= 1.4.3.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A Local File Inclusion (LFI) vulnerability exists in AncoraThemes Exit Game plugin/theme (versions <= 1.4.3) where the application improperly validates user-supplied input used in PHP include/require statements, allowing attackers to include arbitrary local PHP files and potentially execute remote code.

MitigationImplement strict input validation and whitelist-based filtering for all file inclusion paths; disable allow_url_include; ensure all include/require statements use hardcoded base paths and validate that requested files fall within allowed directories.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Locate Exit Game plugin/theme and identify version
    Search the web server filesystem for directories named 'exit-game', 'exit_game', or similar case variations. Check for version.php, version.txt, or plugin/theme header comments that declare the version number.
    Affected if The installed version is 1.4.3 or lower, or no version can be determined but the product is identified as AncoraThemes Exit Game.
  2. Identify PHP files containing include/require statements
    Search all .php files within the Exit Game installation directory for patterns like 'include(', 'require(', 'include_once(', 'require_once(' using grep or similar tools.
    Affected if Any include/require statements accept variables or parameters without hardcoded paths.
  3. Check for user input flow to file inclusion functions
    Examine PHP files that use include/require and trace whether $_GET, $_POST, $_REQUEST, or similar superglobal variables are passed directly to these functions.
    Affected if User-supplied input from GET/POST parameters is used directly in include/require statements without validation.
  4. Identify the vulnerable parameter endpoint
    Locate the specific script that handles file inclusion requests. Look for parameters that accept file paths (commonly 'file', 'page', 'path', 'template', 'include', 'req', or similar).
    Affected if A URL parameter controls which file gets included and the application does not validate the path against a whitelist.
  5. Verify lack of path validation
    Inspect the code around include/require statements to confirm there is no basename(), realpath(), or whitelist check that ensures the requested file is within an allowed directory.
    Affected if The application includes files based on user input without validating that the path is within allowed directories.

A user is affected if they have AncoraThemes Exit Game version 1.4.3 or lower installed AND the application accepts user-controlled input in file inclusion functionality without proper path validation.
